Question

resolva as equações do 2° grau

a)x2+10x+24=0

Answer 1

x²+10x+24=0
a=1
b=10
c=24

Δ=b²-4ac
Δ=10²-4.1.24
Δ=100-96
Δ=4

x=-b⁺₋√Δ / 2a
x=-(+10)⁺₋√4 / 2.1
x= -10⁺₋2 /2

x'= -10+2/2
x'= -8/2
x=-4

x''= -10-2/2
x''= -12/2
x''=-6

Answer 2

x²+10x+24=0

Δ=b²-4.a.c
Δ=10²-4.1.24
Δ=100-96
Δ=4

x=-b+-√Δ  = 10+-√4 =10+-2 =10+2/2=12÷2= 6
     ₋₋₋₋₋₋--    ---------    --------   10-2/2=8÷2= 4
